Applicable Products and Categories of This Article

IMPORTANT: This Answer is for TVs other than Android TV. For Android TV, refer to  The Wi-Fi signal drops or intermittently disconnects. (Android TV)

NOTE: If the TV cannot connect to Wi-Fi at all, refer to The TV (other than Android TV) cannot be connected to the Internet: how to perform a network diagnosis

If the Wi‑Fi signal occasionally or frequently disconnects, check the following items.

  1. The Wi-Fi signal strength is weak.
    If the signal is weak, signal drops might be reduced by placing the Wi-Fi router close to the TV.
  2. The TV is too close to the router.
    If the TV and router are too close, communication may not work.  
    We recommend that you keep the distance between the TV and router at more than 1 meter.
  3. Other Wi-Fi devices are used in the same network.
    If other devices download large-sized files such as videos, the network speed might slow down. In this case, we recommend that you stop downloading videos.
  4. Reset the TV / router / modem
    By resetting these devices, the Wi-Fi signal connectivity might be improved.
    To reset the TV, refer to  How to perform a power reset on a Sony television.  
    To reset the router or mode, refer to the operating instructions of the device.
  5. Interference from other wireless devices, electric equipment, or the environment
    If many wireless devices or electric equipment such as microwaves are used at home,
    the Wi-Fi performance of the TV may be affected.
    Try to turn off these wireless/electric devices or keep them away from the TV.
    Electromagnetic interference may also occur depending on the environment in which the TV is installed. If you can change the environment, change the installation location and check if the performance improves.
     

     Devices that may cause electromagnetic interference

    Environments that may cause electromagnetic interference 

     - microwave ovens 
     - cordless phones
     - Bluetooth devices
     - garage door openers 
     - wireless toys, etc
     - Places that generate electromagnetic interference such as near large transmission lines 
     - Places that generate static electricity
     - Places where the walls, desks, or doors have metal surfaces, etc.
  6. Frequency band setting of the Wi-Fi router
    Depending on the Wi-Fi router, both 2.4 GHz and 5 GHz frequencies may be available.
    We recommend that you use the 5 GHz frequency band if it is available.

    If you continue to experience network issues after following all of the steps above, we recommend using a wired LAN connection from your modem or router.
